Engineering for High-Concurrency Result Day Spikes
Building a student portal presents a unique engineering challenge: on regular days, daily active users may be modest (100–300 visits). But on examination result announcement days, thousands of anxious students and parents refresh the portal simultaneously.
If architected poorly on a monolithic server, the portal crashes within 30 seconds.
The Recommended Decoupled Tech Stack:
1Frontend: React with Tailwind CSS and TanStack Query for smooth client-side caching.
2Authentication: Secure Phone OTP or Roll Number + Password with JWT stored in HTTP-only cookies.
3Database Layer: PostgreSQL with connection pooling (PgBouncer) or Supabase to prevent connection exhaustion.
4Caching & Static Artifacts: Render report cards and fee slips into static signed PDFs cached on Cloudflare CDN, avoiding repeated heavy database queries.
